Why preventive maintenance pays off
A rooftop unit is a major investment, and regular maintenance protects it. Skipping routine service lets small issues, like dirty coils, worn belts, or low refrigerant, grow into expensive breakdowns. A well-maintained RTU delivers real benefits.
- Fewer unexpected breakdowns and less costly downtime
- Lower energy bills, since a clean, tuned unit runs more efficiently
- Longer equipment life, protecting your investment
- More consistent comfort for your staff and customers

Rooftop unit questions, answered
How long does a commercial rooftop unit last?
With regular maintenance, a commercial RTU typically lasts around 15 to 20 years. Good preventive care can extend that, while neglect tends to shorten it.
Should I repair or replace my rooftop unit?
Repair usually makes sense for a unit within its lifespan with an isolated issue. Replacement is often smarter for older units with rising energy bills, frequent breakdowns, or declining performance.
How often should a rooftop unit be serviced?
Most commercial RTUs benefit from preventive maintenance at least twice a year, typically before the heating and cooling seasons, to keep them efficient and reliable.
What are the signs my RTU needs repair?
Watch for rising energy bills, uneven temperatures, frequent breakdowns, weak airflow, and unusual noises or odours from the unit.
